Not sure where to discuss this...

Since there has only been ONE other Final 6 Finale (Cambodia) I thought it might be useful to see what type of Immunity Challenges were in the Finale of Cambodia.

Final 6 Immunity challenge: The castaways raced to assemble puzzle steps on a staircase. After correctly placing all the steps, the castaways then raced to the top to complete a sliding puzzle. The first player to solve their puzzle won immunity. Challenge from Thailand and Redemption Island.

Spencer maintained his lead to win immunity defeating Jeremy, Keith, Kelley, Kimmi, and Tasha.

Final 5 Immunity challenge: The castaways raced through obstacles to retrieve six bags of puzzle pieces. The first castaway to retrieve all six bags and solve the puzzle won immunity. Challenge from South Pacific

Kelley defeated Keith (Jeremy, Spencer and Tasha) to win immunity.

Final 4 Immunity challenge: The castaways, with one hand tied behind their back, dropped a ball into a metal chute, which traveled down a spiraling metal track and exited out of one of two points. The castaway would had to catch the ball and drop it back into the chute at the top. Every few minutes, an additional ball would be added to the track until seven balls were simultaneously going around the track. A turnstile gate in the middle of the track would rotate, causing the balls to alternate exiting out of the two exits. If a ball exited the track and was not caught, the castaway was eliminated; the last one remaining won immunity. Challenge from Tocantins.

Jeremy beat Spencer (Kelley and Tasha) to win the final challenge.
